INVENTOR ATTORNEY Patented Aug. 14, 1934 UNITED STATES FATENT OFFIE 1 Claim.

The object of thepresent invention is to provide a new lace fabric which may be defined as a Swiss and square ground lace employing a warp, and embodying five threads, to wit, warp, spool,

Swiss, square ground and bobbin threads. The

new lace fabric is an improvement upon the ordi nary square ground lace fabric and Swiss lace fabric customarily manufactured on Nottingham lace curtain machines, inasmuch as the new fabric embodies two fillings and in addition, square ground net.

The invention will be described with reference to the accompanying drawing in which Fig. 1 is a diagrammatic view showing the guide bars, threads and a bobbin with its carriage together with a jacquard controlling intercepter.

Fig. 2 is a schematic plan View showing an en bodiment of the new fabric.

' sible traverses of the spool thread.

Fig. 4 is a schematic plan view showing the traverses of the square ground thread. By reference to Fig. 1, it will be seen that in the manufacture of the new fabric on ajacquard control Nottingham lace machine, an additional thread guide bar is introduced, the machine embodying four bars, to wit, a spool bar 19, a Swiss bar 20, a beam bar 21 and a warp bar 22. A jacquard control intercepter 23 is employed for each spool thread a and its companion Swiss thread I). At 24 I have shown one of the bobbins in its carriage 25, the bobbin thread being indicated at c. The laces is indicated at 26 and the horizontal line of lace formation at 27.

ground thread in its traverse crosses two wales so that the horizontal square ground ties'will be doubled. The'traverse of the Swiss thread bar is arranged the reverseof the traverse of the spool thread bar. In other words, the ties of the Swiss thread are made by interception and the Swiss threads pillar when not intercepted. To illustrate this, reference to Fig. 1 will show the intercepter 23 in engagement with the spool thread but not intercepting the Swiss thread. In view of the reverse traverse of the spool and thread bars 19 and 20, this position of the elements will cause the spool thread to pillar with the warp and the Swiss thread to pillar with .the warp. When the intercepter releases the spool thread, the latter will make a three gait tie. not intercepted and therefore are uniformly tied with the warp to form a square net. As stated above, the traverse of the square ground threads In the application of my novel fabric, the square The beam or square ground threads are' in the present fabric is three gaits so that the horizontal square ground ties will be double.

In Fig. 2 I have shown the square ground threads merely by horizontal lines in order that the laying of the Swiss and spoolthreads may be more clearly illustrated. I have also omitted the bobbin threads for the same reason. The bobbin threads, as customary, will tie the spool. Swiss and beam threads to the warp.

By referring to Fig. 2, it will be noted that the warp threads are shown at l, 4, 7, l0, l3, and 16. Two sets of filling threads are shown comprising, namely; Swiss threads and the spool threads. To better illustrate the position of these threads, I have shown the spool threads in full lines and the Swiss threads in dotted lines. In Fig. 2 the first spool thread is shown at 2.

, The intercepters at both sides of that thread be- Fig. 3 is a schematic planview showing the posing in, the thread pillars until it reaches the second horizontal line formed by the beam threads, and at that point, one intercepter being out, the thread traverses to the right, back to the left, to the right again, and thence to the left. At the last named point, both intercepters are in, and the thread pillars to the bottom of the lace section shown in the sketch. In Fig.2, the Swiss thread is shown at 3 in dotted lines. The intercepters being out, the Swiss thread pillars until it reaches the third line 7 of horizontal beam threads. At such point, one intercepter is in, and one out, so that the Swiss thread is traversed to the right, thence to the left, thence to the right, thence to the left, and from such point pillars downward without further traverse.

Referring again to Fig. 2, the spool thread 6 pillars until it reaches the first line of horizontal beam threads shown in the sketch, one intercepter being out and one in, the thread is traversed to the right, thence to the left, thence to the right, thence to the left; both intercepters being in, the thread pillars until it reaches the first point of tie at which point one intercepter is out, whereupon the spool thread traverses to the left, thence to the right, thence to the left, thence to the right, from which point it pillars without fur- 10o ther traverse. The Swiss thread 5 pillars to the third horizontal line of beam threads because of the intercepters are set out. At that point, one intercepter being in and one out, the thread traverses to the right, whereupon,- both intercepters being in, the thread traverses across warp thread 4 to warp thread 1, thence back across warp thread 4 to warp thread 7, thence to the left across warp thread 4 to warp thread 1, thence back across warp thread 4 to warp thread 7. no,

At this point, one intercepter is out so that the said Swiss thread is traversed to the left to Warp thread A, thence to the right back to warp thread '7, thence to the left to its original position adjacent warp thread 4. At the last named point, the intercepters move out and as both intercepters are out, Swiss thread 5 pillars.

Referring again to Fig. 2, the third spool thread is shown at 8. Both the intercepters are in, the spool thread pillars on warp thread '7 until it reaches the first horizontal beam threads, the latter acting with the warp to form the net. At

this point, one intercepter being out, the said.

spool thread 3 traverses to the right to warp thread 10, whereupon both intercepters being out, spool thread 8 is traversed to warp thread 4, thence across warp thread 7 to warp thread 10, thence back to the left across the warp thread 7 to warp thread A, whereupon one intercepter being in. spool thread 8 is traversed to theright at which point both intercepters are inv and the said spool thread 8 pillars to the third horizontal line of beam threads. At this point, one intercepter is moved out and the other remaining, the spool thread 8 is traversed to the right to warp 10, thence back .to warp '7, thence to the right to warp 10, thence to the left from which point it pillars. Associated with warp thread 7 is Swiss thread 9. That thread pillars to a point below the third line of horizontal beam threads whereupon one intercepter being out, Swiss thread 9 is traversed to the left to warp thread A, thence to the right back to warp thread 1, thence to the left to warp thread 4. At the last named point, both intercepters being in, Swiss thread 9 traverses to the right across warp thread '7 to warp thread 10, thence to the left across warp thread 7 to warp thread A, thence to the right back to warp thread-10 at which point one inter cepter being out and one in, the Swiss thread 9 is traversed to its original relation with warp thread 7 and pillars on the warp thread.

The fourth spool thread is shown in Fig. 2 at 11, wh re it pillars along warp thread 10 to the first horizontal net threads. One intercepter being out, spool thread 11 is traversed to warp 13, whereupon both intercepters being out, spool thread 11 is traversed across warp thread 10.to warp thread 7, thence back to warp thread 13, thence back to warp thread 7, thence to the right back to warp thread 13. At the last named point, one intercepter being in and the other out, spool thread 11 is traversed to the left and to warp thread 10, thence to the right to warp thread 13, thence back to warp thread 10. Both intercepters being in, spool thread 11 pillars a short distance whereupon with one intercepter out, spool thread 11 is traversed to the left to warp thread 7, thence to the right back to warp thread 10, thence to the left to warp thread '7, thence back to warp thread 10. At this point, both intercepters are in and spool thread 11 pillars.

The Swiss thread 12 associated with warp thread. 10 pillars to a point below the third set of 'hori- -zonta1 threads of the net at which point one intercepter being Swiss thread 12 is traversed from warpthread 1% to warp thread 13, thence back to warp thread 10, thence to the right to warp thread 13. At this point, both intercepters are in and Swiss thread 12 is traversed across warp thread 1 to warp thread '7. At this'point,

one intercepter is in and the other out so that.

Swiss thread 12 traverses to the right and to warp thread '10, thence to the left to warp thread '7, thence to the right to warp thread 10, thence to the left to warp thread 7, and thence back to the right to warp thread 10. Both intercepters bein out, the Swiss thread pillars from the last named position.

The fifth spool thread shown in Fig. 2 and indicated at 15 pillars to a point below the first set of horizontal beam threads at which point one intercepter being in, spool thread 15 is traversed to the left to warp thread 10, thence back to Warp thread 13 and thence to the left to warp thread 10. At this point two intercepters being out',' spool thread 15 is traversed to the right across warp thread 13 and to warp thread 16, thence to the left and to warp thread 10, thence to the right to warp thread 15, thence to the left to warp thread 10, thence back to warp thread 16. At this point, one intercepter being in and one out, the said spool thread 15 is traversed back to its initial position relatively to warp thread 13, thence to the right to warp thread 16, thence to'the left to Warp. thread 13. At the last named point, both intercepters being in, spool thread 15 pillars. The Swiss thread 14 associated with warp thread 13 pillars to a point below the third set of horizontal beam threads. At this point one of the intercepters being in, Swiss thread 14.- crossesto the left to warp thread 10, thence to the right to warp thread 13, thence to the left to warp thread 10, thence to the right to warp thread 13, thence to the left to warp thread 10, and thence back to warp thread 13 at which point it pillars.

The sixth spool thread is indicated in Fig. 2 at 17, and it pillars to a point below the second set of horizontal beam threads. At that point, one intercepter being out, spool thread 1'7 is traversed to the left and to warp thread 13,

thence to the right to warp thread 16, thence to the left to warp thread 13, again to the right to warp thread 16, thence to the left to warp thread 13,; then to the right to warp thread 16, from which point it is traversed to the left and to Warp thread 13, thence backto warp thread 16, at which point it pillars. The Swiss thread 18 associated with warp 1'7 pillars from top'to bottom of the lace formation shown in the drawing.

To further illustrate the action of the spool three-gait traverse under control of the intercepters, reference to Fig. 3 will show the possible traverses. To the point 28 the spool thread a has pillared, both intercepters being in. By both intercepters is meant the intercepters at each side of the thread. At point 28 the two intercepters re out and the spool thread is traversed to the right hand warp and thence across the middle warp to the left hand warp, the traverse movements continue until said spool thread reaches the point 29. At such point, both intercepters are in and the spool thread pillars until it reaches the point 30. At that point one intercepter, which may be termed the intercepter at the'left of the thread, is in, so that the thread traverses to the right hand warp and thence to "the middle warp, this action continuing to the point 31. this point, both intercepters being in, the said spool thread pillars to the point 32. At such point, the intercepter to the left is out but the intercepter to the right is in, therefore, the spool thread must traverse to the left, thence back to the center warp thread, thuscontinuing to the point 33, at which point both intercepters being in, the spool thread pillars.

Inasmuch as the Swiss thread bar has a traverse opposite that of the spool thread bar, the action of the intercepters will be the reverse of those for the spool thread.

The diagrammatic view, Fig. 4, illustrates the traverse of the beam bar thread, or square ground thread, the beam bar making its cycle in four complete motions. From the point 34 to the point 35 the beam thread traverses to the left three gaits, remains adjacent the left hand warp to the point 36 from which point it traverses to the right one gait and to 3'7, thence to the left one gait to point 38. From this point it traverses to the right three gaits, thence to the left one gait to the point 39, thence to the right one gait to the point 40, where it remains in position to the point 4.1 for repeat.

The embodiment illustrated in Fig. 2 is merely one of many Swiss and spool thread arrangements possible under the invention as will be understood by those skilled in the art and upon referenoe to possible three-gait traverse of either of the threads. The characteristic of the invention,

therefore, is a lace fabric embodying a square net formed by warp and square ground threads and filling comprising laterally traversed and pillared Swiss and spool threads, the three last named threads being tied to the warp by the usual bobbin threads. By employing Swiss and spool threads of contrasting shades or colors, as, for example, ecru and light brown, old patterns of hand made square ground lace may be closely simulated by reason of the construction, the lace being strong and durable.

Having described my invention, what I claim and desire to secure by Letters Patent, is as follows:

A lace fabric comprising a warp, square ground threads laid in double horizontal ties, spool and Swiss threads employed as fillings, the spool and Swiss threads being independently and reversely traversed, and bobbin threads tying the'spool, Swiss and square ground threads to the warp.
